Abundancia y distribución de la liebre ibérica (Lepus granatensis Rosenhauer, 1856) en el Parque Natural de la Sierra de Mariola (Alicante-Valencia)

Abstract

Abundance and distribution of the Iberian hare (Lepus granatensis Rosenhauer, 1856) in the Sierra de Mariola Natural Park (Alicante-Valencia) The Iberian hare (Lepus granatensis Rosenhauer, 1856) is a species of great value in Spanish Mediterranean ecosystems for several reasons, such as its interest to hunters, its contribution to soil fertility and plant diversity, and its role as prey. However, factors such as fragmentation, degradation and loss of habitat and diseases, predation and high pressure hunting are having a detrimental effect on the conservation of the species. It is therefore of interest to determine the abundance and distribution of the Iberian hare in areas of the peninsula where there are insufficient data to establish guidelines for conservation and sustainable management of hare populations in the peninsula. Our goal was to assess the abundance and distribution of the Iberian hare in the most widely used areas of a mountainous Mediterranean landscape in the Iberian peninsular (Mariola Mountain Park, located between the provinces of Alicante and Valencia). Data obtained from studies conducted in transects from 2008 to 2010 showed that intra-annual abundance was highest in spring (KIA half of 0.26 hares/km) and lowest in winter (average 0.075 KIA hares/km). As to their preferences in relation to land use, abundance was highest in the matrix of dry groves (KIA half of 0.33 hares/km) and irrigated groves (average 0.2 KIA hares/km). The matrix of natural vegetation and agricultural abandonment had low numbers of hares, with values of 0.083 and 0.033 hares/km, respectively.
